Preparation of pigs before entering the fermentation bed barn

Pigs should be immunized and dewormed before entering the pen. According to the feeding density, one piglet is 0.8 square meters and one big pig is 1.2 square meters. The density is too high, the cushion material can not digest and absorb so much feces and urine, and it is not economical if the density is too small. However, we recommend a maximum density of 1.2 square meters per head, as this can greatly improve the life of the cushion.

One day after the fermentation mattress material is opened or covered with forage, the fermentation bed surface temperature is lower than 30 ℃, and the pig can enter the column. When the temperature is above 15 ℃, the fermentation mattress does not need to be covered with film or straw.
